RESUMEN

INTRODUCTION: Bile acid sequestrants (BAS) are an option for microscopic colitis (MC) refractory or intolerant to budesonide. There are inconsistent data on the prevalence of bile acid malabsorption (BAM) and utility of bile acid testing in MC. The aim of this systematic review and meta-analysis was to evaluate these outcomes. METHODS: A systematic search of randomized control trials and observational studies of adults with MC treated with BAS was conducted using MEDLINE, Embase, Cochrane, and Scopus from inception to January 22, 2024. Data were extracted on (i) prevalence of BAM, (ii) clinical response and adverse events, and (iii) recurrence after BAS discontinuation. Data were pooled using random-effects models to determine weighted pooled estimates and 95% confidence intervals (CIs). RESULTS: We included 23 studies (1 randomized control trial, 22 observational), with 1,011 patients with MC assessed for BAM and 771 treated with BAS. The pooled prevalence of BAM was 34% (95% CI 0.26-0.42, I2 = 81%). The pooled response rate with BAS induction for all patients with MC, irrespective of BAM, was 62% (95% CI 0.55-0.70, I2 = 71%). There was a higher pooled response rate in patients with BAM compared with those without BAM ( P < 0.0001). The pooled rate of BAS-related adverse effects was 9% (95% CI 0.05-0.14, I2 = 58%). DISCUSSION: One-third of patients with MC had BAM, and almost two-thirds of all patients responded to BAS with limited side effects. Patients with MC and BAM were more likely to respond to therapy, supporting the value of bile acid testing.

RESUMEN

We performed an updated study to investigate the rates of urinary tract infections (UTIs) in patients with recurrent Clostridioides difficile infection (CDI) who received fecal microbiota transplantation (FMT) for CDI. We found a significant reduction in number of UTIs after FMT compared to patients who received antibiotics for CDI treatment. After FMT, we also observed a trend towards reduction of antibiotic resistance in organisms causing UTI.

RESUMEN

BACKGROUND: Fecal microbiota transplantation (FMT) is a safe and effective therapy for recurrent Clostridioides difficile infection (CDI). Data on FMT for CDI in patients with underlying inflammatory bowel disease (IBD) are emerging but conflicting. We performed a systematic review and meta-analysis to describe the efficacy and safety of FMT for CDI in IBD and its impact on IBD outcomes. METHODS: A systematic search of multiple databases including Embase, Scopus, and Web of Science was performed. Our primary analysis focused on pooled rate of CDI resolution after single and multiple FMTs in IBD patients. Additional analyses included rates of IBD-associated outcomes (flare, surgery, symptom improvement) after FMT. The random-effects model was used to calculate pooled rates. RESULTS: Among 457 adult patients, 363 had CDI resolution after first FMT with a pooled cure rate of 78% [95% confidence interval (CI): 73%-83%; I2 =39%]. Overall pooled rate cure rate with single and multiple FMTs was 88% (95% CI: 81%-94%; I2 =73%). The pooled rate of an IBD flare after FMT was 26.8% (95% CI: 22.5%-31.6%; I2 =9%) and of colectomy was 7.3% (95% CI: 4.7%-10.5%; I2 =56%). Among 141 pediatric patients, 106 had CDI resolution after first FMT with pooled cure rate of 78% (95% CI: 58%-93%; I2 =59%). Overall pooled cure rate with single and multiple FMTs was 77% (95% CI: 50%-96%; I2 =63%). The pooled rate of an IBD flare after FMT was 10.8% (95% CI: 5.7%-18.5% I2 =43%), and of colectomy was 10.3% (95% CI: 2.1%-30.2% I2 =23%). CONCLUSIONS: FMT appears to be a highly effective therapy for preventing recurrent CDI in patients with IBD. Patients who fail a single FMT may benefit from multiple FMTs.

RESUMEN

INTRODUCTION AND OBJECTIVES: Practicing physicians often hesitate to use statins and/or other lipid-lowering therapies in NAFLD due to concern for hepatotoxicity. The aim of this study is to examine the safety of lipid lowering therapies in NAFLD patients. MATERIALS AND METHODS: Data from randomized control trials (RCT) among NAFLD patients were pooled to examine the effect of lipid-lowering therapies on liver chemistry, lipid profile, and liver histology. Results are reported as the mean difference of the change (pretreatment-posttreatment) between the treatment and control group. RESULTS: A total of 21 placebo-controlled RCT on 1900 patients (304 receiving statins, 520 other lipid-lowering therapies, and 61 combinations) were treated for 26 weeks [Interquartile range (IQR): 17.5-52 weeks]. Pooled data showed an improved lipid profile without any worsening of ALT, AST, total bilirubin, or alkaline phosphatase at the end of the treatment period. NAFLD activity score improved with other lipid-lowering agents but not with statins. There was no change in individual components of NAFLD activity score or fibrosis stage. CONCLUSION: This meta-analysis of randomized controlled trials examining statins and/or other lipid-lowering therapies in NAFLD patients showed no evidence of worsening liver chemistry. Studies with longer use of lipid-lowering therapies are suggested to examine the benefit of liver histology among patients with NAFLD.

RESUMEN

BACKGROUND AND AIMS: The EndoRotor, nonthermal, powered endoscopic debridement (PED) instrument (Interscope Inc, Whitinsville, Mass, USA), is a novel device used in the GI tract. It uses adjustable suction and a rotary cutting blade to precisely resect mucosal and submucosal tissue. Our aim was to assess the technical feasibility, safety, and efficacy of PED using the EndoRotor device. METHODS: This was an Institutional Review Board-approved, multicenter, retrospective review. Patients underwent PED with the EndoRotor device from August 2018 to September 2019 at 4 high-volume U.S. centers. Patient demographics, indication for PED, and procedural and histopathologic data were recorded. RESULTS: Thirty-four patients underwent PED (41 lesions). The most common indications for PED were colon polyps (18, 52.9%) and Barrett's esophagus (8, 23.5%). Most lesions (35, 85.4%) were resected previously for the same indication using standard techniques. Technical success was achieved in 97.6% of lesions (n = 40). Clinical success was achieved in most patients who underwent a follow-up examination (19, 79.2%). Intraprocedural bleeding (in 10 patients) was managed endoscopically; no EndoRotor-related perforations occurred. Three postprocedural adverse events occurred: self-limited chest pain in 1 patient and delayed bleeding in 2. CONCLUSIONS: The EndoRotor is a novel, effective, and safe PED device for endoscopic resection of flat and polypoid lesions in the colon and foregut. It may have a promising role in the endoscopic management of naïve and scarred mucosal lesions based on this initial experience. Further prospective studies are needed to clarify its role in endoluminal resection.

RESUMEN

Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent Clostridioides difficile infection (CDI), with ~15% 1-year recurrence rate. Small studies have identified variable risk factors associated with FMT failure. We, therefore, performed a systematic review and meta-analysis to evaluate the predictors of FMT failure. A systematic search of Medline, Embase, and Web of Science was performed from January 2013 up to June 2020. Meta-analyses were performed using random-effects models and pooled adjusted odds ratios for risk factors reported in ≥2 studies were calculated. Overall, 2671 patients with recurrent CDI who underwent FMT in 12 studies were included. FMT failure occurred in 454 patients (16.9%) with median follow-up of 3 months (range 2-7.7 months). A total of 9 risk factors were identified in ≥2 studies. Meta-analysis showed that use of non- CDI antibiotics, presence of inflammatory bowel disease, poor quality of bowel preparation, CDI-related hospitalization before FMT, inpatient FMT, and severe CDI were associated with statistically significant increased risk of failure after FMT. Increasing age, female gender, and immunocompromised status were not associated with increased risk for FMT failure. Several risk factors (both modifiable and non-modifiable) are associated with FMT failure. Lower use of antibiotics in the post-FMT period and good bowel preparation at the time of FMT are associated with lower risk of failure after FMT. Additionally, patients with non-modifiable risk factors should be counseled to be particularly alert about recurrent symptoms after FMT.

RESUMEN

BACKGROUND AND GOALS: Clostridioides difficile infection (CDI) recurs in 10% to 15% after fecal microbiota transplantation (FMT). We identify predictors, and describe management and outcome of patients with recurrent CDI after FMT in a predominantly outpatient cohort. METHODS: A nested case-control study of patients undergoing FMT for recurrent CDI from August 2012 to January 2017 was performed. FMT failure was defined as recurrent diarrhea with positive C. difficile stool test during follow-up (≥2 mo). Controls (patients without FMT failures) were matched to cases 1:1 for sex and timing of FMT±1 month. RESULTS: Overall, 522 patients underwent FMT; 70 [13.4%; median age 53.8 years (range, 18 to 89 y), 54.3% females] recurred within a median 5.6 months (range, 0.2 to 34.9 mo). Number of prior CDI episodes, prior CDI treatment, and prior CDI-related hospitalizations were similar in cases and controls. Systemic antibiotics after FMT (54.3% vs. 21.4%, P<0.0001), inflammatory bowel disease (IBD) (34.3% vs. 15.7%, P=0.01), pseudomembranes at FMT (4.3% vs. 0%, P=0.03), and poor bowel preparation (68.5% vs. 31.4%, P=0.01) were associated with FMT failure. On multivariate analysis, IBD [odds ratio (OR) 4.34; 95% confidence interval (CI), 1.24-15.15], systemic antibiotics (OR 7.39; 95% CI, 3.02-18.07), and poor bowel preparation (OR 3.84; 95% CI, 1.59-9.28) predicted FMT failure with an area under the curve of 0.78. Among FMT failures, 37 (52.8%) were managed with antibiotics, 32 (45.7%) with repeat FMT after antibiotics and 1 with colectomy. CONCLUSIONS: Use of systemic antibiotics, IBD, and poor bowel preparation predict FMT failure. Patients with FMT failure can be managed with antibiotics and/or repeat FMT.

RESUMEN

INTRODUCTION: Cryotherapy is a cold-based ablative therapy used primarily as second line therapy in patients with Barrett's esophagus (BE) who have persistent dysplasia after undergoing endoscopic treatment with radiofrequency ablation (RFA). Few studies have described the use of cryotherapy as a primary treatment modality for dysplastic or neoplastic BE. AIM: To evaluate the efficacy of cryotherapy as primary treatment of dysplastic and/or neoplastic BE by conducting a systemic review and meta-analysis. METHODS: A systematic search of Medline, Embase, and Web of Science was performed from January 2000 through March 2020. Articles included were observational studies and clinical trials which included patients who had biopsy confirmed dysplastic or neoplastic BE (i.e., high grade dysplasia (HGD), low grade dysplasia (LGD) or intramucosal adenocarcinoma (ImCA)), underwent ≥1 session of cryotherapy, and had a follow-up endoscopy. Primary outcomes were pooled proportions of patients achieving complete eradication of dysplasia (CE-D) and/or intestinal metaplasia (CE-IM) by using a random effects model. RESULTS: Fourteen studies making up 405 patients with follow-up ranging from 3-54 months were included. In 13 studies, a total of 321/405 patients achieved CE-D with a pooled proportion of 84.8% (95% confidence interval [CI] 72.2-94.4), with substantial heterogeneity (I2 = 88.3%). In 13 studies, a total of 321/405 patients achieved CE-D with a pooled proportion of 84.8% (95% confidence interval [CI] 72.2-94.4), with substantial heterogeneity (I2 = 88.3%). Subgroup analysis of only high-quality studies revealed a pooled proportion of CE-D 91.3% (95% CI, 83.0-97.4, I2 = 69.5%) and pooled proportion of CE-IM of 71.6% (95% CI, 59.0-82.9, I2 = 80.9%). Adverse events were reported in 12.2% patients. CONCLUSION: Cryotherapy is a safe and effective primary therapy for dysplastic/early neoplastic BE. CE-D and CE-IM rates are comparable to those for other ablation modalities, including RFA. Cryotherapy should be considered for primary therapy of dysplastic BE and early esophageal neoplasia.

RESUMEN

BACKGROUND: Fecal microbiota transplantation (FMT) is highly effective for treating recurrent Clostridium difficile infection (CDI) in observational studies (>90%), but cure rates in clinical trials are lower. We performed a systematic review and meta-analysis to assess the efficacy of FMT for recurrent CDI in open-label studies and clinical trials . METHODS: A systematic search from January 1978 to March 2017 was performed to include clinical trials of FMT for CDI. We analyzed CDI resolution by calculating weighted pooled rates (WPRs). RESULTS: Thirteen trials were included, comprising 610 patients with CDI treated with single FMT. Overall, 439 patients had clinical cure (WPR, 76.1%; 95% confidence interval (CI), 66.4%-85.7%). There was significant heterogeneity among studies (I2 = 91.35%). Cure rates were lower in randomized trials (139/216 patients; WPR, 67.7%; 95% CI, 54.2%-81.3%) than in open-label studies (300/394 patients; WPR, 82.7%; 71.1%-94.3%) (P < .001). Subgroup analysis by FMT delivery modality showed lower cure rates with enema than colonoscopy (WPR, 66.3% vs 87.4%; P < .001) but no difference between colonoscopy and oral delivery (WPR, 87.4% vs 81.4%; P = .17). Lower rates were seen for studies including both recurrent and refractory CDI than for those including only recurrent CDI (WPR, 63.9% vs 79%; P < .001). CONCLUSIONS: FMT was associated with lower cure rates in randomized trials than in open-label and in observational studies. Colonoscopy and oral route are more effective than enema for stool delivery. The efficacy also seems to be higher for recurrent than for refractory CDI.

RESUMEN

Fecal microbiota transplant (FMT) is recommended for Clostridium difficile infection (CDI) treatment; however, use in solid organ transplantation (SOT) patients has theoretical safety concerns. This multicenter, retrospective study evaluated FMT safety, effectiveness, and risk factors for failure in SOT patients. Primary cure and overall cure were defined as resolution of diarrhea or negative C difficile stool test after a single FMT or after subsequent FMT(s) ± anti-CDI antibiotics, respectively. Ninety-four SOT patients underwent FMT, 78% for recurrent CDI and 22% for severe or fulminant CDI. FMT-related adverse events (AE) occurred in 22.3% of cases, mainly comprising self-limiting conditions including nausea, abdominal pain, and FMT-related diarrhea. Severe AEs occurred in 3.2% of cases, with no FMT-related bacteremia. After FMT, 25% of patients with underlying inflammatory bowel disease had worsening disease activity, while 14% of cytomegalovirus-seropositive patients had reactivation. At 3 months, primary cure was 58.7%, while overall cure was 91.3%. Predictors of failing a single FMT included inpatient status, severe and fulminant CDI, presence of pseudomembranous colitis, and use of non-CDI antibiotics at the time of FMT. These data suggest FMT is safe in SOT patients. However, repeated FMT(s) or additional antibiotics may be needed to optimize rates of cure with FMT.

RESUMEN

BACKGROUND AND AIMS: Clostridium difficile infection (CDI) has been associated with an increased mortality risk among patients with inflammatory bowel disease (IBD) in multiple observational studies. We performed a systematic review and meta-analysis to help clearly define the magnitude of risk in IBD patients with and without CDI, and to assess the risk in individual IBD subtypes. METHODS: A systematic search of multiple electronic databases was conducted for observational studies reporting the risk of mortality in IBD, stratified by the presence of CDI. Weighted summary estimates were calculated using generalized inverse variance with random-effects model. Study quality was assessed using the Newcastle-Ottawa scale. RESULTS: Ten observational studies were identified (8 from North America and 2 from Europe) and included 40,700 IBD patients with CDI and 1,320,764 IBD controls without CDI. Overall, IBD patients with CDI had a higher risk of mortality compared with IBD patients without CDI [odds ratios (OR), 4.39; 95% confidence interval (CI), 3.56-5.42; I=93%]. The results were stable in high-quality studies and in hospitalized patients. When patients were stratified by IBD type, CDI was associated with increased mortality in patients with ulcerative colitis (7 studies) (OR, 4.39; 95% CI, 3.44-5.61; I), but not in patients with Crohn's disease (4 studies) (OR, 2.21; 95% CI, 0.84-5.77; I). Individual studies were limited by an inability to control for IBD disease activity and therapeutic interventions. CONCLUSIONS: On the basis of 10 observational studies with at least moderate quality, CDI seems to increase mortality risk in IBD, particularly in ulcerative colitis. These findings are a cause for concern and suggest that CDI should be managed aggressively in patients with IBD.

RESUMEN

BACKGROUND: Decreases in clinical response of Clostridioides difficile to antibiotics used for its treatment have raised concerns regarding antibiotic resistance. We conducted a systematic review and meta-analysis to study the resistance rates of C. difficile to various antibiotics over time. METHODS: We systematically searched MEDLINE, Embase, and Web of Science from inception through 03/31/2017 for observational studies assessing antibiotic resistance rates in C. difficile. Weighted summary estimates were calculated using inverse variance heterogeneity models [MetaXL software (v. 5.3)]. A priori subgroup analyses were done (by study year, continent, susceptibility testing method, origin of isolates); ribotype 027 strains were analyzed separately. RESULTS: From 1982 to 2017, 60 studies (8336 isolates) were analyzed. Fifty-three studies reported vancomycin resistance; weighted pooled resistance (WPR), 2.1% (95% CI, 0%-5.1%; I2 = 95%). Fifty-five studies reported metronidazole resistance; WPR, 1.9% (95% CI, 0.5%-3.6%; I2 = 89%). Compared to the period before 2012, vancomycin resistance increased by 3.6% (95% CI, 2.9%-4.2%; P < 0.001) after 2012, and metronidazole resistance decreased by 0.8% (95% CI, 0.1%-1.5%; P = 0.02). No isolates were resistant to fidaxomicin. CONCLUSION: Resistance of C. difficile to vancomycin is increasing, with a smaller, declining resistance to metronidazole; there is significant heterogeneity between studies. Ongoing monitoring of resistance to commonly used antibiotics is required.

RESUMEN

Background: The choice of antibiotics for systemic infections in patients with a high risk of Clostridium difficile infection (CDI) remains a clinical practice dilemma. Although some studies suggest that tetracyclines may be associated with a lower risk of CDI than other antibiotics, other results are conflicting. We conducted a systematic review and metaanalysis of studies that assessed the risk of CDI with tetracyclines compared to other antibiotics. Methods: We conducted a systematic search of Medline, Embase, and Web of Science from January 1978 through December 2016 to include studies that assessed the association between tetracycline use and risk of CDI. Weighted summary estimates were calculated using generalized inverse variance with a random-effects model using RevMan 5.3. Study quality was assessed using the Newcastle-Ottawa scale. Results: Six studies (4 case control, 2 cohort) with patient recruitment between 1993 and 2012 were included. Metaanalysis using a random-effects model, demonstrated that tetracyclines were associated with a decreased risk of CDI (odds ratio [OR], 0.62; 95% confidence interval [CI], 0.47-0.81; P < .001). There was significant heterogeneity, with an I2 of 53% with no publication bias. Subgroup analysis of studies that evaluated the risk of CDI with doxycycline alone also demonstrated a decreased risk of CDI (OR, 0.55; 95% CI, 0.40-0.75; P < .001). Conclusions: Metaanalyses of existing studies suggest that tetracyclines may be associated with a decreased risk of CDI compared with other antimicrobials. It may be reasonable to use tetracyclines whenever appropriate to decrease CDI associated with antibiotic use.

RESUMEN

Background: There has been an overall decline in intensive care unit mortality over the past 2 decades, including in patients undergoing intubation and mechanical ventilation (MV). Whether this decline extends to patients with metastatic cancer remains unknown. We analyzed the outcomes of patients with metastatic cancer undergoing intubation/MV using the National Hospital Discharge Survey (NHDS) database from 2001 to 2010. Methods: Diagnosis and procedure codes were used to identify patients with metastatic cancer who underwent intubation/MV. Demographics, diagnoses, length of stay (LOS), and discharge information were abstracted. Multivariate linear and logistic regression models with weighted analysis were conducted to study trends in outcomes. Results: During the 10-year study period, 200,350 patients with metastatic cancer and who underwent intubation/MV were identified; the mean age was 65.3 years and 46.2% were men. There was an increase in the total number of patients with metastatic cancer who underwent intubation/MV during the study period, from 36,881 in 2001-2002 to 51,003 in 2009-2010 (P<.001). The overall inpatient mortality rate was 57.3%, discharge to a care facility (DTCF) rate was 40.9% among patients alive at discharge, and mean LOS was 11.1 days. No significant trends were seen in rates of mortality, DTCF, or LOS from 2001 to 2010. Conclusions: In this national database, there was an increase in the number of patients with metastatic cancer who underwent intubation/MV. These patients had high rates of inpatient mortality and DTCF, which did not improve during the study period. Therefore, novel solutions are required to improve outcomes for these patients.

RESUMEN

GOALS: To evaluate our experience with stool donor recruitment, screening, retention, and donor perception for fecal microbiota transplantation (FMT). BACKGROUND: Multiply recurrent Clostridium difficile infection is being increasingly managed with FMT from donor stools. However, donor selection and recruitment is challenging due to lack of standard evidence-based guidelines, donor exclusion criteria, frequency of screening and donor commitment. METHODS: Data on donors screened using institutional guidelines with history, blood and stool testing and their perspectives on donation were analyzed. RESULTS: Overall 42 potential donors (21 known and 21 standard) were prescreened. Of known donors (median age 34 y, 66.6% female), none failed prescreening, blood or stool tests. Twelve standard donors (57%) failed prescreening based on history (depression, diarrhea, autoimmune disease, recent antibiotic exposure, colon polyps, pregnancy). Nine (median age 35 y, 44.4% female) passed blood and stool testing. On repeat screening, 3 were excluded (2-positive stool shiga toxin (asymptomatic), 1-pregnancy). One donor opted out and 5 became long-term donors; 3 have donated >50 times and 2 have donated >25 times. On the basis of donor perception questionnaire, most standard donors were aware of FMT for C. difficile infection as a treatment option and would not consider 3-monthly blood and stool testing inconvenient. CONCLUSIONS: A significant proportion of healthy individuals who volunteered to become a standard donor failed prescreening and were not subjected to blood and stool testing. Repeat testing for asymptomatic donors may be a barrier to donor retention. Universal guidelines are needed to develop strategies to facilitate donor screening.

RESUMEN

AIM: We performed meta-analysis to determine effect of alcohol relapse after liver transplantation (LT) for alcoholic cirrhosis on graft histology and survival. METHODS: Studies were selected using following criteria: (a) LT for alcoholic cirrhosis, (b) reporting data on liver histology and/or patient survival among relapsers and abstainers, (c) minimum follow-up of 3 years. Random effects model was used to pool data to compare relapsers and abstainers on liver histology and patient survival. RESULTS: On analysis of seven studies, pooled prevalence of self-reported alcohol relapse was 26.3% (18.0-36.7%) over median (range) follow-up of 6.0 (3.7-8.3) years, with annual alcohol relapse rate of 4.7% (3.0-6.4%) for any alcohol use and 2.9% (0.5-5.3%) for heavy alcohol use. Relapsers compared to abstainers had higher odds for graft steatosis [4.1 (2.4-6.9)], steatohepatitis [4.5 (1.4-14.2)], alcoholic hepatitis [9.3 (1.01-85)], advanced fibrosis or cirrhosis [8.4 (3.5-20)]. Relapsers were over 3-fold more likely to die at 10 years of follow-up: [3.67 (1.42-9.50)] without differences in overall or 5-year survival. Recurrent alcoholic cirrhosis occurring in 9% of biopsied patients and 2% of all transplants was responsible for about 20% of all deaths on follow-up after LT. Extra-hepatic malignancy, and cardiovascular events were common causes for patient mortality. CONCLUSION: Alcohol relapse after LT for alcoholic cirrhosis negatively impacts the graft and long-term patient survival. Studies are needed to develop strategies to reduce alcohol relapse after LT for alcoholic cirrhosis. SHORT SUMMARY: Alcohol relapse in liver transplant recipients can negatively affect graft histology and patient survival. Strategies to reduce alcohol relapse are needed to preserve graft function?

RESUMEN

Broad-spectrum antibiotics for recurrent multidrug-resistant urinary tract infections (UTIs) disrupt the gut microbiome and promote antibiotic resistance. Fecal microbiota transplantation led to resolution of recurrent Clostridium difficile, significantly decreased recurrent UTI frequency, and improved antibiotic susceptibility profile of UTI-causing organisms.

RESUMEN

Background: Patients with cancer have several risk factors for Clostridium difficile infection (CDI), but the impact of CDI on outcomes in this population needs elucidation. We analyzed the incidence of CDI and its impact on outcomes in patients with cancer using the National Hospital Discharge Survey (NHDS) database from 2001 to 2010. Methods: Diagnosis codes were used to identify patients with cancer and CDI events. Demographics, diagnoses, length of stay (LOS), and discharge information were abstracted. Multivariate linear and logistic regression models with weighted analysis were conducted to study CDI incidence and CDI-associated outcomes. Analyses were performed using SAS version 9.4. Results: During the 10-year study period, 20.1 million discharges had a cancer diagnosis. CDI developed in 1.09% of patients with cancer versus 0.77% of patients without cancer (adjusted odds ratio [aOR], 1.28; 95% CI, 1.28-1.29; P<.001). The incidence of CDI in patients with cancer increased during the 10-year study period (64.7 per 10,000 discharges in 2001-2002 to 109.1 in 2009-2010; P<.001). In multivariable analysis, compared with patients with cancer without CDI, patients with cancer and CDI had a longer mean LOS (5.67 days; 95% CI, 5.39-5.94) and higher rates of in-hospital mortality (aOR, 1.18; 95% CI, 1.16-1.20) and discharge to a care facility (aOR, 1.74; 95% CI, 1.72-1.75; all P<.001). Conclusions: In this national database, CDI incidence increased significantly in patients with cancer over the study period and was associated with prolonged hospitalization, increased mortality, and discharge to a care facility. Despite increased attention, CDI remained a serious infection and merits appropriate prevention and management.
